H Company released Holo4, a new series of generalist computer-use agentic models in two sizes — 27B dense and 35B-A3B Mixture of Experts — both available on the H Models API, alongside an updated Holotron 3 called Holotr…
A developer described an internal platform, built on a single MCP server, that lets non-engineers ship their own AI tools to production from a chat by enforcing a server-side gate that blocks plan confirmation until clar…
A developer built Handshake, an agent that checks whether a Model Context Protocol (MCP) server will keep working with a given client after the 2026-07-28 spec revision, which removes initialize, Mcp-Session-Id, ping, lo…
Google's Chrome browser has added WebMCP support to its inspector, according to a report on the feature. WebMCP is described as moving quickly and on track to become a widely used web standard, and the author says they h…
ZYK Labs released AI Beacon, an open-source inbox that lets AI agents initiate conversations with the project's operators without an account or CAPTCHA, exposing a JSON API, private conversation tokens and a separate ope…
Google assigned CVE-2026-14540, a CVSS 8.0 server-side request forgery in its MCP Toolbox for Databases, where the HTTP client was initialized without a CheckRedirect policy or target IP validation, allowing a crafted pa…
Agnostic-ai released v0.71.0, adding user-level MCP server installation for Claude Code, Codex, Cursor, Copilot, Gemini, Qoder, OpenHands, and Augment, plus a settings spec that sets default model and effort per tool. Th…
Vectorize CEO Chris Latimer said coding agents are storing API keys, credentials, and sensitive documents in plain text on developer machines and in cloud services, and that attackers could plant poisoned memories throug…
A developer built a confusion-telemetry system for an MCP server that logs each recovery message as a structured Application Insights row tagged with a sentinel slug, tool name, schema version, and a description hash com…
Cartograph, a federated Model Context Protocol (MCP) proxy, reduces agent-visible tool discovery from O(n) catalog traversal to O(k) progressive disclosure, exposing three proxy tools instead of 374 definitions on a 22-s…
A team released Muslim, a production Arabic voice AI platform for grounded Islamic knowledge, built on a real-time pipeline of NeMo Arabic ASR, an OpenAI-compatible LLM endpoint and self-hosted TTS, with retrieval routed…
A new arXiv paper (2609.30341v1) presents an architectural mediation approach using the Model Context Protocol (MCP), implemented through the Eunomia Agent, to connect large language model (LLM) agents with governed data…
A new open protocol lets AI agents discover a service's feedback policy at the `.well-known/agent-feedback.json` discovery document, submit structured bug reports and friction signals via HTTP POST to `/api/v1/feedback`,…
A developer tested how Claude Code 2.1.278 expands environment variables in .mcp.json by wiring a dependency-free stdio MCP server into the config seven times and logging what the spawned process actually received. The p…
A developer detailed a pattern for building an MCP-compatible client that generates per-platform configuration files for clients like Cursor, Claude Desktop, and Windsurf, rather than hand-pasting JSON. The approach pins…
Stepgate, an MCP server released on Hacker News' Show HN, runs agent procedures written as YAML "stepfiles" and shows the calling agent one step at a time, advancing only when that step's gates pass. Each stepfile declar…
Arsumbris released an early alpha of its agent-native IDE for typed knowledge, currently macOS-only, built on a type engine and extensible agent framework that indexes cross-repo markdown and YAML files into a typed, que…
A developer demonstrated running an AI agent loop inside a browser tab using Pyodide (CPython compiled to WebAssembly) for the agent logic and a local Ollama model as the reasoning backend, rather than driving a separate…
LoreDocs launched a free local-first knowledge vault tier that stores up to three independent vaults, full-text search, and document versioning in a user-owned SQLite file without requiring an account. The tool runs as a…
Five Mac apps connect Claude to Apple apps, ranked by setup effort: Macuse ($49 once, 100 free tool calls a day) and Pomeroy ($19 once, 50 free actions a week) configure everything from the app, iMCP (free, MIT) writes C…
